A once-in-a-generation estate has hit the market in Dallas' Preston Hollow neighborhood. Located at 9511 Inwood Rd., the home is being offered for sale for the first time in more than a century, having remained under the stewardship of the same family since at least 1940 when the current home was built.

Situated on nearly three acres on a corner lot, it's an English-style estate surrounded by century-old hardwoods and manicured landscaping, creating a private sanctuary in the middle of the city.

There's a main residence, guest quarters, and two workshops, one featuring a rail-mounted hoist and enhanced electrical systems.

Listed for $7,500,000, the home has 4,675 square feet with four bedrooms, 4.5 bathrooms, and a five-car garage.

The property is free from both floodplain and historic designation, allowing a buyer to remodel, rebuild, or (ugh) subdivide. It also has three curb cuts — two on Inwood Road and one on Park Lane — with the possibility of a posh Park Lane address.

It's also zoned for horses and other animals, and a perimeter privacy wall can be added.

According to listing agent Andrea Childress with The Agency Dallas, the property was originally known as Sunnyslope Estate, and was developed more than 100 years ago by oilman M.H. Marr, who was searching for a place to settle with his family when he discovered the tract of land on what was then the edge of Dallas and is now in the heart of Preston Hollow.

Marr's wife, Adah Yale Marr, was known for her prominent social presence, entertaining various figures and hosting business gatherings with Dallas families like the Hunts, Meadows, and DeGolyers among their guests.

Childress calls it "more than just a listing—it’s a landmark."

"Properties like this simply don’t exist anymore, especially with this kind of acreage, location, and legacy,” she says.
